Нижний р д стрелок показывает направлени токов при питании обмотки через выводы 01 и 02 однофазным током, откуда видно, что 2Р, 18.The upper row of arrows shows the direction of the currents when the winding is supplied through the C1-S3 terminals with three-phase current (for the point in time when the current in the C1 phase has the maximum value), from which it is clear that 2P, 2. The lower row of arrows shows the direction of the currents when powered winding through pins 01 and 02 with single-phase current, whence it is clear that 2P, 18.

Вьтолнение обмотки в 48 пазах позвол ет использовать ее дл другоThe winding implementation in 48 slots allows it to be used for other

го диапазона мощностей машины. Кроме того, выполнение обмотки однослойной значительно уменьшает трудоемкость ее изготовлени .go power range of the machine. In addition, the implementation of a single-layer winding significantly reduces the complexity of its manufacture.

Обмотка может примен тьс , например , в одномашинных преобразовател х частоты и числа фаз, а также в бесконтактных машинах переменного тока с совмещенным возбудителем и др.The winding can be used, for example, in single-machine frequency and phase converters, as well as in non-contact AC machines with a combined pathogen, etc.
